Justin Moore has seven No. 1 singles under his belt...and, even better, 10 years of marriage to his wife, Kate!

The "Kinda Don't Care" singer took to Instagram on Saturday (Sept. 30) to commemorate this big anniversary, posting a picture of the couple's 2007 save-the-date invitation announcing their upcoming nuptials.

“To my lovely bride, happy 10th wedding anniversary. This takes me back to when we were youthful... Haha," he quipped.

Moore -- who, at 33, isn't exactly an old man yet -- has four children with his wife and says his family is complete. The couple's first son, South, was just born this June. "My wife wants a boy so bad she can’t stand it," he noted earlier this year. "So she worked on me for about a year. So, she finally got me drunk and took advantage of me,” he joked.
